9-3 Homework Hints!

For problems where you might want to use the Google Calculator make sure you write the word "degrees" in your calculation.

For example, for #10 you might want to calculate something involving tangent. So make sure to type "tan(22 degrees)" or even "tan(22degrees)" into Google Calculator when doing your computation. Otherwise you will end up with an answer more than 100 times wrong!

Why does this happen? If you just type in "tan(22)" it computes the value using another measurement system. Not degrees but radians. Remember, we'll talk more about radians after the Star Test :).
